' surfaces, and furthermore, means are provided for draining off the oil which may leak from the several engine or motor units. so as to eliminate spilling or flooding over the passageways or parts of the floor upon which the operators usually walk.

he invention may best be understood by reference to the accompanying drawings in whicl v V Figure 1 is a plan view of a main frame casting, herein shown as specially adapted for use in an electric locomotive generating its power with a Diesel oil engine, but with the motor operating parts comprising the generating; motor. electrical equipment and other accessories removed from the top of this frame;

Figure 2 is a view part in vertical section and partin side view, of the frame casting shown in Figure 1;

Figure 3 is an enlarged detail section taken on line 33 of Figure 1; and

Figure 1 is an enlarged sectional View taken on line 47- 1 of Figure 1.

Referring to the drawings, my invention is shown applied to a typical frame castof an oil-electric locomotive. In the form shown. this frame comprises a platform having an upper floor 5 and bottom flanges 6 connected by laterally extending vertically disposed webs 7-7, and longitudinally disposed webs 88. The floor 5 has its upper surface suitably arranged to support the main parts of the motive equipment. it will be understood, however. that my invention is not limited to any particular type of motive equipment, and the arrangement of supporting means shown in the drawings is merely used to illustrate one form in which my invention may be applied. I do not, therefore, show any specific forms of motive apparatus, but will indicate, in

- as bolts.

the drawing, for purposes of illustration, parts or areas of the upper floor of the frame which may be used to support certain motor apparatus. For instance, the central area designated generally by the letter A, may be used for a Diesel engine and generator. The areas indicated by letters B, may contain air compressors; the area, division C, may contain a connection box; the areas D, D, D, fuel oil tanks; the area E, E, water tanks; and the areas F, F controllers for opposite ends of the frame. The elongated areas G, G, may be machined and adapted to form the foundations for vertical partitions, if such are to be used in a locomotive of the general character herein contemplated.

Referring more particularly to the features of invention illustrated in the particular embodiment shown, it will be ob-- served that most of the upper surface of the flooring, not to be occupied by various parts of apparatus, is formed with the usual serrated or checkered upper surface designed to minimize the danger of slipping. In the form shown, the passageway surfaces are formed by a series of serrations 10, 10, of pyramidal form, as best shown in crosssection in Figures 3 and 4, although any similar suitable roughened surface may be utilized for this purpose. It will be understood that these serrations are formed integral with the main frame casting.

At the points where the various parts of the apparatus are to be supported, the casting is provided with raised surfaces or pads, these surfaces being elevated above the topmost points of the serrations 10, 10, clearly shown in Figures 3 and 4C, and being machined on a plane surface so as to receive the various parts of the motor equipment. Thus the area for the Diesel engine and generator, illustrated by letter A, has a raised portion or pad 11, suitably machined to receive such equipment which may be secured thereto by any usual means, such Similarly, the areas B, B, have raised surfaces or pads 12, 12, to receive their respective parts, while areas C, D, E and F have raised portions or pads 13, 14:, 15 and 16, respectively. In case partitions are to be used, the parts G, G, are also machined so that said partitions may be fitted and secured thereto. As will be seen from the sectional views 2, 3 and 4, all of the pads 11, 12, 13, 14: 15 and 16, which are finished to support their respective elements, are substantially the same height, the arrangementbeing particularly designed. so that all of said pads may be machined in one planing operation, without interfering with the intermediate serrations 10, 10, covering the various passageways or walking areas.

In connection with the supporting areas upon which the various motor parts are mounted, I provide a plurality of grooves, surrounding); th same, as for instance grooves 20, 21 and 22. Thus in the case of the centrally disposed Diesel engine and generator, the groove 20 is cast in the frame floor, so as to surround the central area A, this groove being formed so as to drain to some central point or points, as for instance, the holes 20 20, on opposite sides of the motor. Thev arrangement is such that any oil or fuel leaking from the Diesel engine or generator will be caught in this groove and drained from the upper floor surface, and thus eliminate the leakage of oil to Sl rounding areas of the floor which are used for passageways, which otherwise would soon become slippery with oil and thus very dangerous on account of the possibility that operators mayslip thereon and be thrown into the machinery. Similarly, the groove 21 may be formed about the areas D, D, (herein described'as containing fuel oil tanks), and drain in a hole 21 while groove 22 may be formed about the areas E, (herein described as containing water tanlrs). Similarly any other apparatus which contains 031 or other fluid capable of leakage over the floor of the frame, may be surrounded by grooves, if desired. The holes 20, 21 and 22 may be arranged to drain through the base frame, r may be provided with a suitable receptacle 24-, to retain the drippings, if desired.

I claim as my invention:
